To (IN whom if muy4 concern Be it known that I, llnxs'r lV. JonNsoN, acitizen of the United States, and residing at New York, in the county ofNew York and State of New York, have invented certain new and usefulImprovements in Shoe- Polishing Machines. of which the following .is aspecification. such as will enable those skilled iu the art to which itappertains to make and use the same.

l This invention relates to machines for polishing shoes. and the objectthereof is to provide an improved machine of this class which isautomatic in operation and which set for operation bv the, insertion ofa coin and which is set in operation bv placing the foot on a'suitablesupport and forcing said support downwardly, which operation spraysthcshoe with liquid blackingand then puts in motion the polishingbrushes with which the machine is provided. and the construction andoperation heilig such that when the brushes, having completed their workot' polishing the shoe the operation of the machine is .tut.omatici"ystopped, b v breaking the circuit of an electric motor b v which themachine is operated. and at which time the foot is removed vfrom thesupport and the operative parts returned to their normal position andautonmtiaillv locked.

The invention is fully disclosed in the tollowing spcciiication of whichthe accompanying drawings form a part, in which thc separate parts of myinvention are :designated `b v suitable reference. 'characters in eachot' the views, and in which the bottom part of the Figure l. is alongitudinal vertical section ot my machine on the line 1-1 of F ig. 2`;Fig. Q a transverse vertical Sectio-11 on the line 2-2 of Fig. 3; Fig.`3 a plan view of machine with the casing removed and parts broken away;Fig. .1. a side view of the machine on a reduced scale and with parts ofthe construction broken away; F ig. 5 a central vertical section throughthe top part of the machine and showingr the parts in inoperativeposition; and Fig. G a View similar to Fig. 5 but. showing the parts inan operative position.

l, designates a casing which houses the entire mechanism and iscoinposed of a ver tic-.d top partI Q, and a horizontalbase 3. The toppart 2 comprises a front wall 4,

and a removable `back 5, and is closed at the top and sides. as shown.

'lfhc front wall t is provided with an opening (5, which enters into acoin receptacle 7,and is closed by a door 8, having a suit able lock Sl.and above the opening l pro vide a coin support t0. which 't'orlns oneside ot a slot l1, and passing throltgh th'e front wall l ot the top 2of the casing l, and slidablv mounted in the slot ll is a plinger barlit, having a thumb piece lil, at its outer end and provided with acircular coin aperture l-t, about cent 'al ot' its length which isadapted to receive a coin l5, when the machine is to be operated, aswill hereinafter appear. The plunger bar' i2. `s further provided. nearits inner end with spaced perforated lugs lt'. between which is pivoteda link 1T which is pivotallv connected at its rear end with a switch arm1S. of a bell crank lever 19. mounted as shown at '20, in the ltop ofthe casing l, and having a short arm 2l. to which is connected a wire orcable 22. as shown.

ln order to prevent unscrupulous persons` vfrom operating the machinewithout dcpositing the necessary coin in the aperture 14. lV provide astop dog Q25, pivotcd at Qt, immediately above thc plunger bar 1Q, andwhich is provided with a forwardly and do\\'i1\vardl v directed nose 25.which is tensionallv held in contact with thc plunger bar 12. and willenter the coin aperture 1.4. as it passes underneath, it there is nocoin therein. and stop the inward movement of the plunger bar 1L. lt.however. the necesl sary coin is deposited in the aperture 14. the noseof/ thc dog 28, will ride over it. as the plunger bar 1Q. is ot the samethickness as the coin, as shown in Fig. 5, and the dog 223, is providedwith a tail piece 2(3, connected with one cud ot a pull spring 2T. thcother end being anchored to the casing at 28.

livoted at QS). in the casing is a trip lever 30. having a downwardlydirected arm 3l, ranging across thc path of niovement of the plunger barl2. and a backwardly directed arm .32. havingl a trip wire or cable 33,c0n ncctcd therewith, and which is'adaptcd to rest on a stop pin 34,when the mechanism is in itsl inoperative position and locked as will behereinafter explained.

The trip lever 30. is so placed that,` it

Civ

there is no coin placed in the aperture 14,

and the plunger bar 12, is forced inwardly, the nose 25 of the dog 23,will stop the inward movement of said plunger bar 12 before the rear endthereof contacts with the downwardly directed arm 31.

The switch arm 18 of the bell crank lever 19 is adapted, when the partsare in the operative position as shown in Fig. to make electricalconnection between two contacts 35, which forni the terminals of a motorcircuit 36. i

Secured to the back 5, of the casing is a bracket .37, having a groovedwheel 38, mounted therein andaround and over which is passed a chain 39,one end of which is provided with a weight 40, the other end beingcarried down to and around a grooved wheel 41, mounted at 42, and thenforwardly to and around another grooved w-lieel 43,

; mounted at 44, to a stationary table 45, and

then downwardly to an eye or staple 46, fixed on a vertically movablebar 47.

The stationary table 45, is lsupported within the base 3, of the casingl, by standards 48, which are bolted to the table 45, and to the bottom49 of the base 3, as .shown and these standards 48, are provided withintegral keepers 50, in which are movable lock bolts 51, having reducedextensions 52,

assinr throii h can ieces 53 between which and the bolts 51,' are placedpush springs 54, which normally tend to force the bolts, 51, againstbars 55, vertically movable in central bo-res 5G, in the standards 48,and these bars 55, are connected at the upper ends thereof with a footrest 57, which when the parts are' in the normal inoperative positionassumes the elevated position shown in dotted lines in Fig. 1, and whenin this position the bars 55, and foot rest 57 are held against downwardmovement by the lock bolts 51, project-ing into the bores 56, andunderthe lower ends ofthe hars 55, as will be readily understood.

Connected with the reduced extensions 52 of the bolts 5l are wires orcables 58, which are passed around grooved wheelsf), :arried in abracket 60, secured to the stationary table 45, and these wires orcables58, are

Vbrought together at 61, and connected to the trip wire or cable 33which is passed around a grooved wheel 62, mounted in the base 63, ofthe casing, as shown.

The standards 48 are further provided with longitudinal slots 63,through which project perforated pins 64, to which are connected wiresor cables 65 and (S6. which are passed under and around groovcd wheels(37 and 68, and the Wire or cable 65 is connected to the downwardlydirected arm (if), of a bell crank lever 70, which is pivotcd at 71, inthe base 3 of the casing.

The shorter arm 72, of the crank lever 70, has connected thereto a Wireor cable 78 which passes over and around a grooved wheel 74 rotatablymounted inthe base 3 and then backwardly and is connected to a grooved,wheel 75, around which passes a wireor cable 76,*both ends of which areconnectedas at 77, to a brush strap 78, provided with long bristles 79,as shown.

The wire or cable 66, at the opposite end of the footrest from thewire/or cable G5, is passed upwardly and around a grooved wheel 80,rotatably mounted in the base 3, and then backwardly and is connected tothe lower end 81, of a lever arm 82, loosely mounted at 83, in a bracket84, secured to the back 5, of the base 3' of the vcasing 1.

The lever arm 82, is extended abo-ve the bracket 84, and is connected at85, With a wire or cable 8.6, to which is secured a grooved wheel 87,around which is passed a wire or cable 88, both ends of which aresecured as at 89, to a brush strap 90, having` long bristles 91, asshown, and the brush straps 7 8 and 90 are U-.shaped in form and arcpositioned so that the open sidesk are adjacent and this constructionforms` an elliptical band brush whichl surrounds the shoe when inoperation, and when given av quick circular reciprocatory, movement,thoroughly brushes the shoe as will be readily understood.

The vadjacent ends of the U-shaped brush straps 78 and 90 are providedwith perforated angle plates 92, between which are placed cross-heads93, having longitudinal reduced extensions 94, passing loosely throughthe angle. plates 92', and provided with nuts 95, between which and theangle plates 92, are placed spiral springs 96, which are carried on theextensions 94, asshown, and the cross-heads 93 are connected by integralright angle extensions 97, to blocks 98, slidably mounted on horizontalbars 99, mounted in fixed `standards 100, secured to the table 45.-

The slidahle blocks 98, have short pins 101, on which ai'epivotallymounted one end of pitman rods 102 and 103 the opposite ends of saidpitman rods being carried on wristA pins 104 and 105 which are carriedrespectively oii a gear wheel 106, and a balance wheel 107, fixed to theopposite ends of a rotatable shaft 108, mounted in suitable standardbearings 109 and 110, and the wristA pins 104 and 105 are arrangedopposite of cach other as indicated on dotted lines in (Fig. 1, so thatwhen one of the sliding blocks reaches its outward limit of movement theopposite block has just reached its inward limitof movement, and thisconstruction gives the band brush at opposite sides an op 4positereciprocatory movement Asimilar to that used by boot blacks in polishingshoes. Y

'lhe standard bearing 110, is provided with a supplemental bearing 1.11,extending upwardly and'slightly backwardly and car- 120,in theSupplemental bearing 111.

ltrip pin 115, carried by the gear wheel 1013,

and a cam disk 116, is also fixed to the shaft 112, and is provided witha cam face 117, adapted to co-act with a beveled nose 11S, of u leverarm 119, pivotally mountednat Y forward end of the lever arm 119, isconnected to the lower end of the wire or cable 22', and, when the parteare in the operative position shown in Figs. 1 and G, and after "theshaft 108, has made a predetermined number of revolutions,determined bythe number of pins in the disk 113, in this case it"being ten, the cameyface 117, will operate the lever arm 119, to exert a pull on the wireor cable 22, which Will throw the switch arm 18, away from the contacts35, and

vbreak the motor circuit-to stop the mechanism.

The motor circuit 3G, coniprlses, in addl- `tion to the contacts andswitch arm 18, a

battery 121, and a mechanically operated blade switch 122, secured inthe base of the casing, which comprises .l standard 121-1. an insulatingblock 121, having` springl blades 125 and 120, secured thereto, one o iwhich, the blade 125, being backed up by a set screw 127, the blade 126being in the path of a spring pressed plunger 128, having an enlargedhead 129, movable in1a suitable keeper, as at 130, and one edd of whichis provided witha beveled face 131, against which the lower end 'of`thevertically mov-, able bar 55, impinges to force the head 129, and aplunger 128 backwardly against the `spring blade 126, to' cause it tocontact with the blade 125 to close the motor circuit.

The motor terminals are shown at 1212 and 133, and a conductor 131 isconnected to the terminal 133, and with 4the switch blade 1213, anotherconductor 1,35, is connected to the switch blade 125, and through thebattery to one of the contacts 2.15, and another conductor 13G, isconnected to the other of the contacts and with the motor terminal 132.

In order to give a high polish to the top of `the toe part of the shoe,I provide a swinging brush 137, which operates in a horizontal planeover the front of'the shoe and swings upwardly and baclnvardly,l out ofsight, when not in use.` Mounted on the extreme rear end of the table415, is a stand-- ard 138,11aving a socket 139 in its top to receii'e apivot pin 14:0, which is provided with f, an annular groove 141, adaptedto receive seI the end of a retaining screw 112. The pivot pin iscarried by a forked block 113, through which is passed a shaft141,`on\\vliich is mounted, in the forked block `143, the re'- ducedshank 145, of the brush 137, which is provided with a tail piece 146, tolimit its upward and backward movement, as will be readily understood.

The lever arm S2, is provided with an angular extension 147, andconnected therewith is a wire or cable 148, passing over and around agrooved wheel 149, mounted in the base` 1-1 o1' the casing; and is thenconnected with the shank 145, ot' the brush 137 at 150.

'lhe motor is shown at 151, the motor shal't at 152, and the power geara't 153, which is meshed with the gear 1011, and drives the machine whenin operation.

l`he foregoing all pertains to the control and operation of thepolishing mechanism and .l will now describe the automatic pneumaticmeans for spraying the shoe with liquid blacking' as it enters the baseJ1 of the casing and before tht polishing means is set in operation.

The base 3 o1 the casing is provided with an opening 154, through whichthe foot rest 5T, normally protrudes slightly, it being nornmlly heldelevated as lndicated by the dotted lines in Fig. 1 and full lines inFig. 1, by the weight 40, as will be readily understood.

When it is desired to get a shine. a coin in Figs'. and causes a pull tobe exerted on` the wiresl or cables 22 and 38, and this closes the motorcircuit through the switch arm 18.`

rI`he pull on the wire or cable. 22, throws the beveled nose 11S, downin the path of the cam face 11T, while the pull on the wire or cable321, withdraws the lock-bolts 51, from under the lower ends of the barso5. The toot is now placed on the foot rest, 57, and sutlicient pressureis placed on the foot to depress the foot. rest against the action oitbe weight #1-0. As thefoot rest descends; air is 'forced throughflexible tubesv155, through tbc instrumentality ot' piston rods 1515,pistons 157, and cylinders 15b;` the pist'onrods 1511', being secured tothe descending foot rest 57. while the cylinders 15S, are secured to thetable Lt5. The cylinders are provided just below the upward limit ofmovement of the pistons 157, with air inlets 159, which are closed justas soon as thc',

pistons start downward.

The cylinders are provided nearthe lower ends thereof with air outlets100, and the tubes 155 are connected with these outlets as at 1111 andsaid tubes 155, are. connected at or near the top ot' the base 3 of thecasing, with horizontally movable metallic pipes 11.12, passing throughsuitable keepers 11121, and connected with blacking spray-pipes 1131.ot' semi-elliptic form and provided with small perforations '1135, inthe inner walls thereof and these perforations are carried around therear end of the sprays So that the front as well as the sides ofthe shoewardly over and around grooved wheels 177,

liengitanks 169, to the spray-pipes 164.

In order to separate the spraypipes'164, after the shoe is polished topermit the foot to be withdrawn, I provide slidable bars 170,

mounted in keepers 171, and having reduced 'slidable extensions 172,slidable in keepers 173v Abetweenwhich and the bars'170, are placedsprings 174, as shown, and stop pins 175, are provided to limit theinward inovenient of lthe spray-pipes 164,

It will be understood that all of the keepers 163-171, and 173 aresecured to the underside of the top of the base 3701i the casing.

Secured to-tlie reduced extensions 172, are wires or cables 176, whichare carried outand then downwardly7 and connected with outwardlydirected arms 178,y of bell crank levers i179, pivoted at 180, inbrackets 181,

'secured to the side walls of the base 3 of the casing. and wires orcables 182 are secured at 183, to the vertically movable bar 47, and arepassed under and around grooved wheels 184, and then ,outwardly andsecured to downwardly .directed arms 185 of the bell crank 1ever17 9, asshown.

.In order to impart to the brush 137 a horizontal si'ingingreeiproeatory movement over the toe portion of the shoe, 'I provide thevshaft 144 with slot-ted extensions 186, which are adapted to receivepills 187 car ried by horizontally movable forked bars 188. slidable insuitable keepers 189, secured to the t-wo rear fixed standards 100, andthe rear ends. of the block 98 are provided with lateral shoulders 190,which are adapted to strike the front ends of the opposite bars 188alternately to oscillate the'bar 144, on` its pivot pin lil-0, and givethe brush a swinging:r reciprocatory inoveineit as hereinbefore stated.

lVhen the machine is at rest or when the parts are in the inoperativeposition, the lock bolts 51, range across the bores 56, and underliesthe lower ends of the bars 55, and lock the foot rest 57, againstdownward movement, but when a coin is inserted in the recess 14, and theplunger bar 12, pushed inwardly it strikes the arm 31, ofthe lever 30',and rocks the saine which creates an upward pull on the' trip wire orcable 33 and this operation withdraws 'the lock bolts 51, from the bores56. after which the foot may be `placed on the foot rest 157, andpressed downwardly, and'as the foot rest and its associated partsdescend, the wires or cables (i5, 66 and l82`are drawn outward over the,g'i'ooved wheels 67, 68 and 184 by the action of the springs' 94 and174, which operation forces the brush straps 78 and `90 and .thespray-pipes 164, inwardly in close relation to the shoe to be polished.The` downward movement of the foot rest 57,'also acts to 'release thepull on the wire or cable 148, and

*this permits the brush 137, to drop down' over the toe of the shoe andjust b re the` foot rest reaches its downward limit of movement andafter the shoe has been sprayed with liquid blacking, thelower end ofthe rear bar 55, strikes` the cam face 131,. of thepliinger 128,. andforces said'plunger backwardly to close"the switch 122, kand I startsthe motor which operates the brushes to. polish the shoe.. and ashereinbcfore in ovements of the polishing brushes, the motor circuit isautomatically broken by the cani face 117, operating the 1ever`119 toexert a downward pull on the wire or cable 22 which throwsl the switcharm 18,: out of, en.-

gageinent with the contacts 35 asy will be readily understood. It willalso 4be under# stood that the weight 40, acts to elevate the4 foot rest57, which operation separates tlie` -stated after a predeterminedv.number of so brush straps 78 and 90, as indicated by dot tedlines iiiFig. f5, and also separates the spray-pipes 164. after themacliinecoines to a stop and asthe foot is being withdrawn from the machine.

.l do not desire to be understood as limiting myself to the detailfeatures' and construction and arrangement of parts as herein shown and(lesci'ihed, as it is manifest' that` variations and modificationstherein inay be resorted to, in the adaptionof in v, invention tovaryingyconditions of use without departing from the spirit and scope ofniy invention and improvements. 'I there.- fore reserve the right to allsuch variations and inodications iis'properly fall within the scope ofinv invention and the ternis ofthe following,T claims.
